Description

BACKGROUND OF THE INVENTION

Technical Field

Aspects of the embodiments generally relate to battery operated roller shades, and more particularly to an architectural roller shade housing with adjustable battery compartment.

Background Art

Motorized roller shades provide a convenient one-touch control solution for screening windows, doors, or the like, to achieve privacy and thermal effects. A motorized roller shade typically includes a rectangular shade material attached at one end to a cylindrical rotating tube, called a roller tube, and at an opposite end to a hem bar. The shade material is wrapped around the roller tube. An electric motor, either mounted inside the roller tube or externally coupled to the roller tube, rotates the roller tube to unravel the shade material to cover a window.

Motorized roller shades require local power to be provided to the shade to energize the motor and associated electronics, such as the radio, control circuitry, and encoders, among other devices. Power is typically supplied using power over Ethernet (PoE) wiring, or a local power supply, such as a 24V wall-wart, which may be unsightly and/or challenging to install. In many installations, it may be difficult or impossible to run power and communication wires to a specific location especially in retrofit applications. Battery powered roller shades with radio transceivers for communication provide means to easily install and control a roller shade without running new wires. To enable operation of a roller shade for a prolonged amount of time, many large batteries are required, which present a challenge since they are needed to be stored in proximity to the roller tube in a hidden position. Roller shades typically house the batteries inside the roller tube or roller shade housing out of site from the end user. However, battery replacement in such roller shades is a cumbersome and difficult exercise.

Therefore, a need has arisen for systems, methods, and modes for an improved architectural roller shade housing with adjustable battery compartment that is easily accessible by the user.

Accordingly, the systems, methods, and modes of the aspects of the embodiments described herein can be manufactured by Crestron Electronics, Inc., located in Rockleigh, N.J.

The different aspects of the embodiments described herein pertain to the context of battery operated shades, but is not limited thereto, except as may be set forth expressly in the appended claims. While the roller shade is described herein for covering a window, the roller shade may be used to cover doors, wall openings, or the like. The embodiments described herein may further be adapted in other types of window or door coverings. For example, the battery compartment described herein may be placed in a shade housing designed to house an inverted roller, a Roman shade, an Austrian shade, a pleated shade, a blind type shade, a shutter type shade, a skylight shade, a garage door, or the like.

Disclosed herein are systems, methods, and modes for a battery operated roller shade, and more particularly to an architectural roller shade housing with adjustable battery compartment. Referring to FIG. 1, there is shown a diagram of a battery operated roller shade 100 according to one aspect of the embodiments. Roller shade 100 generally comprises a roller tube 101, a motor drive unit 102, an idler assembly 103, shade material 106, and a hem bar 110. Shade material 106 is connected at its top end to the roller tube 101 and at its bottom end to the hem bar 110. The motor drive unit 102 is adapted to raise or lower the shade material 106 to adjustably cover or uncover a structural opening, such as a window, a door, a wall opening, or the like. For example, in a roller shade application, shade material 106 wraps around the roller tube 101 and is wrapper or unwrapped from the roller tube 101 by rotation of the roller tube 101 by the motor drive unit 102. In various embodiments, the shade material 106 comprises fabric, plastic, vinyl, or other materials known to those skilled in the art.

Roller tube 101 is generally cylindrical in shape and longitudinally extends from a first end 111a to a second end 111b. In various embodiments, the roller tube 101 comprises aluminum, stainless steel, plastic, fiberglass, or other materials known to those skilled in the art. The first end 111a of the roller tube 101 may receive the motor drive unit 102 and the second end 111b of the roller tube 101 may receive the idler assembly 103, although the placement of the motor drive unit 102 and the idler assembly 103 may be reversed.

The idler assembly 103 of the roller shade 100 may comprise an idler pin 109 and an idler body 108 inserted into the second end 111b of the roller tube 101. The idler body 108 may be rotatably connected about the idler pin 109. It is inserted into the roller tube 101 and is operably connected to the roller tube 101 such that rotation of the roller tube 101 also rotates the idler body 108. The idler body 108 may comprise ball bearings therein (not shown) allowing the idler body 108, and thereby the roller tube 101, rotate with respect to the idler pin 109.

During installation, the roller shade 100 is mounted on or in a window between a pair of mounting brackets 203 (FIG. 2). The idler pin 109 may include a pin tip 113 disposed on its terminal end to attach the roller shade 100 to one of the mounting brackets 203. The roller shade 100 may then be mounted to the other mounting bracket 203 by snapping the motor head 127 of the motor drive unit 102 to the mounting bracket 203 or coupling the motor drive unit 102 to the mounting bracket 203 using screws.

The motor drive unit 102 may comprise a motor head 127 including a crown adapter wheel 116, a motor housing 107 containing a motor control module 112 and motor 115 therein, an idler crown wheel 117, a counterbalancing spring 120, and a drive wheel 121. The motor drive unit 102 may be inserted into the roller tube 101 from the first end 111a. The crown adapter wheel 116, idle crown wheel 117, and drive wheel 121 may be generally cylindrical in shape and may comprise a plurality of channels extending circumferentially about their external surfaces that mate with complementary projections radially extending from an inner surface of roller tube 101 such that crown adapter wheel 116, idle crown wheel 117, drive wheel 121, and roller tube 101 rotate together during operation. The drive wheel 121 is operably connected to the motor output shaft of the motor 115 such that rotation of the motor output shaft also rotates the drive wheel 121. The crown adapter wheel 116 and idle wheel 117 may be rotatably attached at two opposite ends of the motor housing 107 via ball bearings to hold the motor 115 concentric to the roller tube 101.

The motor 115 may comprise a brushless direct current (BLDC) electric motor. In another embodiment, the motor 115 comprises a brushed direct current (DC) motor, or any other motor known in the art. In operation, the roller shade 100 is rolled down and rolled up via the motor drive unit 102. Particularly, the motor 115 drives the drive wheel 121, which in turn engages and rotates the roller tube 101. The roller tube 101, in turn, engages and rotates the crown adapter wheel 116, idle crown wheel 117, and idler body 108 with respect to the motor 115, while the motor housing 107, including the motor 115 and motor control module 112, remain stationary. The motor 115 may drive the drive wheel 121 through a series of components that in combination provide efficiency and counterbalancing to the roller shade 100, such as a first stage planetary gear 122, a clutch 123, a final stage planetary gear 124, an output mandrel 125, and a counterbalancing spring 120. In one embodiment, the first and final stage planetary gears 122 and 124 may be configured for providing speed reduction and torque increase to achieve efficient operation of the motor 115. According to another embodiment, the first and final stage planetary gears 122 and 124 may be configured for providing increased speed and decreased torque. The spring 120 may be pretensioned in the factory using the motor 115. The pretensioned counterbalancing spring 120 assists the motor 115 to roll up the shade material 106 throughout the rolling up cycle without the motor 115 requiring to exert much power. According to an embodiment, the battery powered roller shade 100 may comprise similar configuration to the battery power roller shade disclosed in U.S. patent application Ser. No. 15/872,467, filed Jan. 16, 2018, titled “Motor Pretensioned Roller Shade,” the entire contents of which are hereby incorporated by reference.

The motor control module 112 operates to control the motor 115, directing the operation of the motor, including its direction, speed, and position. The motor control module 112 may comprise fully integrated electronics housed on a single or a plurality of printed circuit boards (PCBs). The motor control module 112 may comprise a controller, a memory, a communication interface, a user interface, and a light indicator. The user interface may comprise buttons, such as open and close, as well as a setup button that may allow the user to set the upper limit, the lower limit, the battery replacement limit (discussed below), reverse motor direction as well as assist in acquiring shades to the control system and any other intermediary devices necessary. The buttons may be arranged on the motor drive unit 102 such that they are visible from the front or bottom of the motor drive unit 102. The light indicator, such as a multicolor light emitting diode (LED), may be adapted to display device status, any error feedback, status blink codes, as well as the battery status, such as low-battery conditions. The controller can represent one or more microprocessors, and the microprocessors can be “general purpose” microprocessors, a combination of general and special purpose microprocessors, or application specific integrated circuits (ASICs). The controller provides processing capability for one or more of the techniques and functions described herein. The memory can be communicably coupled to controller and can store data and executable code. In another embodiment, memory is integrated into the controller. The memory can represent volatile memory such as random-access memory (RAM), but can also include nonvolatile memory, such as read-only memory (ROM) or Flash memory.

The communication interface may comprise a wireless communication interface configured for bidirectional communication with other electronic devices over a communications network. A wireless interface can comprise a radio frequency (RF) transceiver, an infrared (IR) transceiver, trace antenna, or other communication technologies known to those skilled in the art. The wireless interface may communicate using a communication protocol, such as the infiNET EX® protocol from Crestron Electronics, Inc. of Rockleigh, N.J., ZigBee® protocol from ZigBee Alliance, Bluetooth, or the like.

The control commands received by the motor control module 112 may be a direct user input to the controller from the user interface or a wireless signal from an external control point. For example, the motor control module 112 may receive a control command from a wall-mounted button panel or a touch-panel in response to a button actuation or similar action by the user. Control commands may also originate from a signal generator such as a timer or a sensor. Accordingly, the motor control module 102 can integrate seamlessly with other control systems using the communication interface to be operated from keypads, wireless remotes, touch screens, and wireless communication devices, such as smart phones. Additionally, the motor control module 102 can be integrated within a large scale building automation system or a small scale home automation system and be controllable by a central control processor, such as the PRO3 control processor available from Crestron Electronics, Inc., that networks, manages, and controls a building management system.

The motor drive unit 102 may be connected to a replaceable power supply 130, such as a plurality of serially arranged batteries. Power supply 130 provides power to the circuitry of the motor control module 112, and in turn the motor 115. The motor control module 112 may be connected to the power supply 130, such as batteries, through power cords 128 and one or more connectivity ports 132. In yet another embodiment, the motor control module 112 may also be connected to a solar panel or a solar collection module placed in proximity to the window to aggregate solar energy and recharge the batteries.

Referring to FIGS. 2-7, where FIG. 2 illustrates a side view of the battery operated roller shade 100 with the battery compartment 201 in a retracted or hidden position within the roller shade housing 200, FIG. 3 illustrates a side view of the roller shade 100 with the battery compartment 201 in a partially extended position with respect to the roller shade housing 200, FIG. 4 illustrates a side view of the roller shade 100 with the battery compartment 200 in a fully extended position; FIG. 5 illustrates a front view of the roller shade 100 with the battery compartment 201 in an extended position and with its door 224 closed, FIG. 6 illustrates a front view of the roller shade 100 with the battery compartment 201 in an extended position and with its door 224 opened, and FIG. 7 illustrates a front view of the roller shade 100 with the battery compartment 201 in a retracted or hidden position.

As seen in FIG. 2, each end of the roller shade 100 may be mounted to a mounting bracket 203. The mounting brackets can comprise similar configuration to the CSS-ARCH3 QMT3 Series Architectural Shade Hardware, available from Crestron Electronics, Inc. of Rockleigh, N.J. Other types of brackets may be utilized without departing from the scope of the present embodiments. The mounting bracket 203 in turn can be surface-mounted on a wall or ceiling or recess-mounted in a pocket or window jamb.

The roller shade 100 further comprises housing 200 which may comprise a first housing portion 211 a second housing portion 212. The first housing portion 211 may at least partially cover or conceal the roller tube 101 from view, including the motor drive unit 102 therein, as well as any of the shade material 106 wrapped around the roller tube 101. The second housing portion 212 may at least partially cover or conceal the battery compartment 201 from view when it is in a retracted position. According to an embodiment, as shown in FIG. 2, the housing 200 may consist of a decorative fascia comprising a front wall 204 that covers the front of the roller tube 101 as well as the battery compartment 201. The housing 200 may further comprise a bottom wall 205 that partially covers the bottom of the roller tube 101 as well as the battery compartment 201 from view. The housing 200 may further comprise an intermediate horizontal wall 206 extending from an inner surface of the front wall 204 to partially segregate the roller tube 101 and battery compartment 201. According to an embodiment, the bottom wall 205 may be partially curved resulting in a curved fascia, as shown in FIG. 2, or alternatively it may be flat resulting in a square fascia. According to a further embodiment, additional covers, such as top and back covers, and a blackout extrusion can be attached to the side mounting brackets 203 or the fascia's front wall 204 to provide additional coverage or blackout for the top and back of the roller tube 101. According to another embodiment, the housing 200 may instead comprise a pocketed construction consisting of a U-shaped extrusion that covers the front, top, and back of the roller tube 101. Alternatively, a G-shaped housing 200 may be used that also partially covers the bottom of the roller tube 101.

Irrespective of the housing type or shape, the housing 200 defines an opening 207 at the bottom that allows the shade material 106 to drop down from the roller tube 101 and out of the housing 200. The housing 200 may be connected to and supported by the pair of oppositely disposed mounting brackets 203, for example by having the fascia snap on the front of each of the mounting brackets 203. Although in other embodiment, the mounting brackets 203 and housing 200 may be an integral component. Referring to FIG. 5, the housing 200 may span the width of the roller tube 101 and may longitudinally extend from a first end 202a to a second end 202b. Referring back to FIG. 2, a battery compartment supporting bracket 215 may be connected at each end 202a-b of the housing 200, each adapted to support and rotatably connect the battery compartment 201 to the housing 200. The housing 200 may comprise a pair of shoulders 232 spaced to retain the battery compartment supporting brackets 215 therebetween. Each supporting bracket 215 may be further secured to the roller shade housing 200 using screw 231.

The battery compartment 201 may be secured to the housing 200 at a position below the roller tube 101 such that it does not impede with the travel of the shade material 106 and/or the hem bar 110 when the battery compartment 201 is in a retracted position. Particularly, when the shade material 106 is raised or lowered between its upper and lower limits, it tends to translate laterally with respect to the roller tube 101—for example from a first drop down position 208, where the shade material 106 is substantially fully lowered or fully unrolled from the roller tube 101 (i.e., at the lower limit), to a second drop down position 209, where the shade material 106 is substantially raised or substantially rolled on the roller tube 101 (i.e., at the upper limit). This is because as the shade material 106 rolls on the roller tube 101, the shade material 106 layers on the roller tube 101 causing the diameter of the shade material 106 on the roller tube 101 to increase and result in the lateral movement of the shade material 106. As such, the drop down position of the shade material 106 is continuously displaced. Accordingly, the battery compartment 201 is secured to the housing 200 at a retracted position shown in FIG. 2 at sufficient distance from the shade material 106 and hem bar 110 such that the battery compartment 201 does not contact the shade material 106 or the hem bar 110 whether it is fully raised or lowered during operation.

Referring to FIGS. 2 and 5, the battery compartment 201 may comprise a tubular body or enclosure designed to maintain a compact and discrete appearance that is easily accessible for battery replacement. Battery compartment 201 longitudinally extends from a first end 221a to a second end 221b, each attached to a respective battery compartment supporting bracket 215. The battery compartment 201 may be made from a lightweight material, such as plastic or a light weight metal extrusion, although other materials may be utilized. The battery compartment 201 may comprise a pair of end caps 216 adapted to close the first and second ends 221a and 221b of the battery compartment 201. Although according to an alternative embodiment, the battery compartment 201 may comprise a single tubular enclosure with integrated closed ends. The battery compartment 201 may be shaped and sized to receive a plurality of batteries arranged in series within the battery compartment 201, for example, eight Alkaline D′ cell batteries 600 (FIG. 6). According to other embodiments, other battery number and sizes may be utilized, such as ‘A’, ‘AA’, ‘C’, or ‘PP3’ cells, or equivalent rechargeable options.

As shown in FIG. 6, the battery compartment 201 may comprise a battery opening 223 traversely extending through its side surface and adapted and sized to receive a battery 600 therethrough and into the battery compartment 201. The opening 223 may be disposed adjacent to a second end 221b (or the first end 221a) of the battery compartment 201. The battery compartment 201 may also comprise a channel 222 that traverses its surface and longitudinally extends from the first end 221a of the battery compartment 201 to the battery opening 223. The batteries 600 may be loaded one by one into the battery compartment 201 through the battery opening 223 at the second end 221b and may be slid towards the first end 221a by accessing the batteries 600 using the longitudinal channel 222 until the battery compartment 201 is full. The battery compartment 201 may comprise a biasing spring 225 adapted to bias and retain the batteries 600 within the battery compartment 201. The battery compartment 201 may further comprise a pair of contacts therein proximate to its first and second ends 221a-b that may be connected via power cord 128 to the motor control module 112 (FIG. 1) to provide contact and power to the batteries 600 therein.

The battery compartment 201 may further comprise a door 224 disposed over the battery opening 223. The door 224 may be adapted to slide from a closed position where it closes the battery opening 223, as shown in FIG. 5, to an opened position where it exposes the battery opening 223 permitting batteries 600 to be inserted therethrough. According to an embodiment, the door 224 may be biased using a spring to generally maintain the door 224 in a closed position (FIG. 5). As such, the door 224 may be slid by a user to an open position (FIG. 6) to insert the batteries 600, and may automatically slide to the closed position (FIG. 5) once it is let go via the biasing spring.

Referring to FIG. 2, each end cap 216 of the battery compartment 201 may comprise a nipple 217 laterally extending therefrom. Each battery supporting bracket 215 may further comprise an L-shaped swing arm 235 that may be pivotally secured at its proximate end 236 to the battery supporting bracket 215, and thereby with respect to the roller shade housing 200, using a rivet or a screw 233 about a pivot axis 230. Swing arm 235 may comprise a longitudinal channel 234 extending therethrough from in proximity to its proximal end 236 to in proximity to its distal end 237. Each nipple 217 on a respective end cap 216 is adapted to slide within and along a respective channel 234 within the swing arm 235.

During normal operation of the roller shade 100, the battery compartment 201 is maintained in the retracted position shown in FIGS. 2 and 7 where the battery compartment 201 is tucked in within the second housing portion 212 of the roller shade housing 200, and hidden by front wall 204 and at least partially by the bottom wall 205. In the retracted position, each swing arm 235 is positioned within the second housing portion 212 such that the channel 234 is oriented at about 45 degree angle with respect to the front wall 204 of the roller shade housing 200. In this position, the channel 234 is declined towards the proximal end 236 of the swing arm 235. The decline of channel 234 causes each nipple 217, and thereby the battery compartment 201, to be positioned within a respective channel 234 proximate to the proximal end 236 of the swing arm 235, and thereby tucked in proximate the front wall 204 of the roller shade housing 200 and away from the shade material 106 and hem bar 110.

According to an embodiment, the motor control module 112 may include battery status monitoring to help users in determining when the batteries 600 need replacement. The motor control module 112 may include circuitry to monitor the power of the batteries through power cord 128 (FIG. 1). With battery status monitoring, the motor control module 112 may send out alerts, letting customer providers and/or end users know when battery replacement is needed. For example, once the battery power reaches a minimum battery threshold, the motor control module 112 may inform the user that the batteries need to get changed, for example, using a native user interface on the motor drive unit 102 or an external user interface point. For example, the motor control module 112 may blink LED in a red color.

In addition, once determining that the battery power has reached the minimum battery threshold, or a second minimum battery threshold, the motor control module 112 may direct the shade material 106 to move to the preset battery replacement limit such that the hem bar 110 is located at a battery replacement position. For example, referring to FIG. 4, the battery replacement position may be a position where the hem bar 110 is positioned at a predetermined distance 401 below the opening 207 at the bottom end of the roller shade housing 200. At this battery replacement position shown in FIG. 4, the shade material 106 may be substantially, but not fully, raised or rolled up on the roller tube 101 (i.e., below the upper limit). As such, the shade material 106 is at a position that is somewhat below the fully-opened position. The layers 405 formed by the shade material 106 on the roller tube 101 cause the shade material 106 to hang at a drop down position 209 that is farther away from the battery compartment 201 than drop down position 208 when the shade material 106 is fully unraveled from the roller tube 101. Being farther away provides more space for the battery compartment 201 to swing down from the shade housing 200. In addition, at the battery replacement position shown in FIG. 4, the hem bar 110 is positioned at a sufficient distance 401 below the opening 207 such that it not in a way when the battery compartment 201 is swung down to an extended position shown in FIG. 4. According to an embodiment, the battery replacement position may be a factory preset limit, or a battery replacement limit preset by the installer. According to an embodiment, the minimum battery threshold may correspond to the minimum runtime required to raise the shade material 106 from a fully lowered or rolled down position (i.e., lower limit) to the battery replacement position shown in FIG. 4.

As such, if the hem bar 110 is positioned below the battery replacement position shown in FIG. 4 (for example when the roller shade 100 is fully closed or partially closed), and if the motor control module 112 detects that the battery power level is at or below the minimum battery threshold, the motor control module 112 may raise the shade material 106 until the hem bar 110 is position at the battery replacement position. Similarly, if the hem bar 110 is positioned above the battery replacement position shown in FIG. 4 (for example when the roller shade 100 is fully opened), and if the motor control module 112 detects that the battery power level is at or below the minimum battery threshold, the motor control module 112 may lower the shade material 106 until the hem bar 110 is position at the battery replacement position. The motor control module 112 may then disable the motor 115 from raising or lowering the shade material 106 until the batteries 600 are replaced. Meanwhile, the motor control module 112 may alert the user that batteries 600 need replacement, as discussed above.

To replace the batteries, each swing arm 235, and thereby the battery compartment 102, may swivel out of the second housing portion 212 about the pivot axis 230 and down through opening 207 in the roller shade housing 200 as shown in FIG. 3 to the extended position shown in FIG. 4. As such, the battery compartment 102 swings down to replace the batteries 600 without removing or moving the roller shade 100 or the roller shade housing or fascia 200. According to an embodiment, the battery compartment 200 may comprise a release latch or lever 501 that generally keeps the battery compartment 200 retained in the retracted position shown in FIGS. 2 and 7. The release latch 501 may release the battery compartment 200 when it is engaged by a user such that the battery compartment 200 swivels and drops down to the extended position shown in FIG. 4, for example via gravity.

According to another embodiment, the battery compartment 200 may be maintained in a retracted position shown in FIG. 2 via a locking mechanism, such as a magnetic lock. The magnetic lock may be operated using the motor control module 112. Once the battery power falls at or below the minimum battery threshold, the motor control module 112 may actuate the magnetic lock to release the battery compartment 200 such that it can drop to the extended position shown in FIG. 4. Although other types of locks or levers operable by the motor control module 112 may be alternatively utilized.

As the battery compartment 200 swings out via the swing arm 235, the channel 234 of the swing arm 235 translates from being declined towards the proximal end 236 of the swing arm 235 to being declined towards the distal end 237 of the swing arm 235. This causes the nipples 217 of endcaps 216 to slide along the channel 234 towards the distal end 237 of the swing arm 235 as shown in FIGS. 3 and 4. As such, in fully extended position shown in FIG. 4, each swing arm 235 is positioned outside the second housing portion 212 such that the respective channel 234 is oriented substantially parallel to the front wall 204 of the roller shade housing 200 and the battery compartment 200 hangs at the distal end 237 of the swing arm 235. The L-shaped swing arm 235 and the longitudinal channel 234 therein help to decrease the radius of rotation of the battery compartment 201 with respect to the roller shade housing 200 about pivot axis 230. This allows the roller shade housing 200 to maintain a small profile while allowing the battery compartment 201 to exit the opening 207 in the roller shade housing 200 and provide the necessary access to the batteries 600 in the compartment 201 in the extended position shown in FIGS. 4 and 5.

As shown in FIGS. 4 and 5, when the battery compartment 201 is swung down, door 224 faces the front of the roller shade 100. According to an embodiment, the biased door 224 will remain closed to prevent the batteries 600 from falling out of the battery compartment 201 during replacement. The user may then slide and open the door 224 to access the battery opening 223 and replace the batteries 600 as shown in FIG. 6. Once the batteries 600 are replaced, the user may release the door 224 to close the battery opening 223 and tilt the battery compartment 201 back into the second housing portion 212 behind the front wall 204 of the roller shade housing 200. The decline of channel 234 toward the proximal end 236 will cause each nipple 217, and thereby the battery compartment 201, to travel along the channel 234 to a positioned proximate to the proximal end 236 of the swing arm 235 and thereby proximate the front wall 204 of the roller shade housing 200. The motor control module 112 may then determine that the battery power has raised above the minimum battery threshold and reactivate the operation of the motor 115 to raise or lower the shade material 106.
